Before you use your masterball on anything I recommend try to catch with the Pokéballs you have first. Hoopa is kinda lacking in some measures, but if you need to use your masterball, use it on Hoopa, because you can only get 1 unbound Hoopa, and soft resetting if you fail will require you to wait way longer to get to battling Hoopa again.
